Wests had the better first half but Magpies dominated the early parts of the second, getting out to a 24-18 lead. After that though, it was one-way traffic, with the Tigers running over the top of the Magpies.

Wests coach Mick Baker said in the end it was a really good win.

"To Magpies' credit they got on a bit of a roll in that second half and we really had to dig in to stop that momentum," Baker said.

"Fortunately we were good enough to turn that around and get some good tries," he said.

Baker said at the end of the game his side completed its final 15 sets, which was a key to the win.

"We knew that if we got into that arm wrestle with Magpies, we were confident in our ability to get over the top of them," he said.
